INITIAL INSPECTION:Be certain to inspect all cartons or crates on each unit asreceived at the job site before signing the freight bill. Verifythat all items have been received and that there are novisible damages; note any shortages or damages on allcopies of the freight bill. In the event of damage orshortage, remember that the purchaser is responsible forfiling the necessary claims with the carrier. Concealeddamages not discovered until after removing the units fromthe packaging must be reported to the carrier within 24hours of receipt.

GENERAL DESCRIPTION:These Water-to-Air Heat Pumps provide the bestcombination of performance and efficiency available.Safety devices are built into each unit to provide themaximum system protection possible when properlyinstalled and maintained.

The AP Water-to-Air Heat Pumps are UnderwritersLaboratories (UL) and (cUL) listed for safety. The water-to-Air Heat Pumps are designed to operate with entering fluidtemperature between 20°F to 80°F in the heating mode andbetween 50°F to 110°F in the cooling mode.

NOTE: 50°F Min. EWT for well water applications withsufficient water flow to prevent freezing. Antifreezesolution is required for all closed loop applications. CoolingTower/Boiler and Earth Coupled (Geo Thermal) applicationsshould have sufficient antifreeze solution to protect againstextreme conditions and equipment failure. Frozen watercoils are not covered under warranty.

NOTE: This product should not be used for temporarilyheating/cooling during construction. Doing so may effectthe units warranty.

MOVING AND STORAGE:If the equipment is not needed for immediate installationupon its arrival at the job site, it should be left in itsshipping carton and stored in a clean, dry area. Units mustonly be stored or moved in the normal upright position asindicated by the "UP" arrows on each carton at all times. Ifunit stacking is required, stack units as follows: Verticalunits less than 6 tons, no more than two high. Horizontalunits less than 6 tons, no more than three high. "Do notstack units larger than 6 tons."

SAFETY CONSIDERATIONS:Installation and servicing of this equipment can behazardous due to system pressure and electricalcomponents. Only trained and qualified personnel shouldinstall, repair, or service the equipment. Untrainedpersonnel can perform basic functions of maintenancesuch as cleaning coils and replacing filters.

WARNING: Before performing service or maintenanceoperations on the system, turn off main power to the unit.Electrical shock could cause personal injury or death.

When working on equipment, always observe precautionsdescribed in the literature, tags, and labels attached to theunit. Follow all safety codes. Wear safety glasses and workgloves. Use a quenching cloth for brazing, and place a fireextinguisher close to the work area.

LOCATION:Locate the unit in an indoor area that allows easy removalof the filter and access panels, and has enough room forservice personnel to perform maintenance or repair.Provide sufficient room to make fluid, electrical, and ductconnection(s). If the unit is located in a confined space suchas a closet, provisions must be made for return air to freelyenter the space. On horizontal units, allow adequate roombelow the unit for a condensate drain trap and do notlocate the unit above supply piping. These units are notapproved for outdoor installation; therefore, they must beinstalled inside the structure being conditioned. Do notlocate in areas that are subject to freezing.

INSTALLATION:NOTE: Remove all shipping blocks under blower housing.Loosen compressor mounting bolts.

MOUNTING VERTICAL UNITS:Vertical units up to six tons are available in left, right, front,or rear air return configurations. Vertical units should bemounted level on a vibration absorbing pad slightly largerthan the base to minimize vibration transmission to thebuilding structure. It is not necessary to anchor the unit tothe floor. (See Figure #1).

MOUNTING HORIZONTAL UNITS:While horizontal unitsmay be installed on anylevel surface strongenough to hold theirweight, they aretypically suspendedabove a ceiling bythreaded rods. The rodsare usually attached tothe unit corners byhanger bracket kits(P/N 930-004, 006). (SeeFigure #2). The rodsmust be securelyanchored to the ceiling.Refer to the hangingbracket assembly andinstallation instructions for details. Model AP025 requiresfour mounting brackets (P/N 930-004). Models AP035 thruAP071 require six brackets (930-006). (See unit horizontaldetail drawing). Horizontal units installed above the ceilingmust conform to all local codes. An auxiliary drain pan ifrequired by code, should be at least four inches larger than

the bottom of the heatpump. Plumbingconnected to the heatpump must not come indirect contact withjoists, trusses, walls, etc.

Some applicationsrequire an attic floorinstallation of thehorizontal unit. In this

case the unit should be set in a full size secondary drainpan on top of a vibration absorbing mesh. The secondary

drain pan prevents possible condensate overflow or waterleakage damage to the ceiling. The secondary drain pan isusually placed on a plywood base isolated from the ceilingjoists by additional layers of vibration absorbing mesh. Inboth cases, a 3/4" drain connected to this secondary panshould be run to an eave at a location that will benoticeable. If the unit is located in a crawl space, thebottom of the unit must be at least 4" above grade toprevent flooding of the electrical parts due to heavy rains.

CONDENSATE DRAIN:

NOTE: If equipped with float style condensate overflowswitch, final adjustment must be made in the field.

A drain line must be connected to the heat pump andpitched away from the unit a minimum of 1/8" per foot toallow the condensate to flow away from the unit.

This connection must be in conformance with localplumbing codes. A trap must be installed in the condensateline to insure free condensate flow. (Heat Pumps are notinternally trapped). A vertical air vent is sometimesrequired to avoid air pockets. (See Figure #3). The length ofthe trap depends on the amount of positive or negativepressure on the drain pan. A second trap must not beincluded.

The horizontal unit should be pitched approximately 1/4"towards the drain in both directions, to facilitatecondensate removal. (See Figure #4)

DUCT SYSTEM:A supply air outlet collar and return air duct flange areprovided on all units to facilitate duct connections. Refer tothe FHP individual data specification sheet for physicaldimensions of the collar and flange.

A flexible connector is recommended for supply and returnair duct connections on metal duct systems. All metalducting should be insulated with a minimum of one inchduct insulation to avoid heat loss or gain and preventcondensate forming during the cooling operation.Application of the unit to uninsulated duct work is notrecommended as the unit’s performance will be adverselyaffected. Do not connect discharge ducts directly to theblower outlet. The factory provided air filter must beremoved when using a filter back return air grill.The factoryfilter should be left in place on a free return system.

If the unit will be installed in a new installation whichincludes new duct work, the installation should bedesigned using current ASHRAE procedures for duct sizing.If the unit is to be connected to existing ductwork, a checkshould be made to assure that the duct system has thecapacity to handle the air required for the unit application.If the duct system is too small, larger ductwork should beinstalled. Check for existing leaks and repair.

The duct system and all diffusers should be sized to handlethe designed air flow quietly. To maximize soundattenuation of the unit blower, the supply and return airplenums should be insulated. There should be no directstraight air path thru the return air grille into the heatpump. The return air inlet to the heat pump must have atleast one 90 degree turn away from the space return airgrille. If air noise or excessive air flow are a problem, theblower speed can be changed to a lower speed to reduceair flow. (Refer to ECM motor interface board section in thismanual and Figure #7)

PIPING:Supply and return piping must be as large as the unitconnections on the heat pump (larger on long runs). Neveruse flexible hoses of a smaller inside diameter than that ofthe fluid connections on the unit. AP units are suppliedwith either a copper or optional cupro-nickel condenser.Copper is adequate for ground water that is not high inmineral content. Should your well driller express concernregarding the quality of the well water available or shouldany known hazards exist in your area, we recommendproper testing to assure the well water quality is suitablefor use with water source equipment. In conditionsanticipating moderate scale formation or in brackish watera cupro-nickel heat exchanger is recommended.

Both the supply and discharge water lines will sweat ifsubjected to low water temperature. These lines should beinsulated to prevent damage from condensation.

All manual flow valves used in the system must be ballvalves. Globe and gate valves must not be used due to highpressure drop and poor throttling characteristics. Neverexceed the recommended water flow rates as seriousdamage or erosion of the water to refrigerant heatexchanger could occur.

Always check carefully for water leaks and repairappropriately. Units are equipped with female pipe threadfittings. Consult the specification sheets for sizes. Teflontape sealer should be used when connecting water pipingconnections to the units to insure against leaks andpossible heat exchanger fouling. Do not overtighten the

AP SERIES

connections. Flexible hoses should be used between theunit and the rigid system to avoid possible vibration. Ballvalves should be installed in the supply and return lines forunit isolation and unit water flow balancing.

ELECTRICAL:(Refer to electrical component box layout, Figure #5)

Field wiring must comply with local and national electriccodes. Power to the unit must be within the operatingvoltage range indicated on the unit nameplate or on theperformance data sheet. On three phase units (single stageunits only) phases must be balanced within 2%.

CAUTION: Operation of unit on improper line voltage orwith excessive phase imbalance will be hazardous to theunit, constitutes abuse and may void the warranty.

Properly sized fuses or HACR circuit breakers must beinstalled for branch circuit protection. See unit nameplatefor maximum fuse or breaker size.

The unit is provided with a concentric knock-out in thefront left corner post for attaching common trade sizes ofconduit, route power supply wiring through this opening.Always connect the ground lead to the grounding lugprovided in the control box and power leads to the powersupply terminal block as indicated on the wiring diagramand Figure #5.

NOTE: Units supplied with internal electric heat requiretwo (2) separate power supplies: one for the unitcompressor and one for the electric heater elements,blower motor and control circuit. Refer to the ELECTRICHEATER PACKAGE OPTION section and Figure #9 for wiringinstructions, minimum circuit ampacities and maximumfuse/breaker sizing.

ECM INTERFACE BOARD:

THERMOSTAT CONNECTIONS:Thermostat wiring is connected to the 10 pin screw typeterminal block on the lower center portion of the ECMInterface Board. In addition to providing a connecting pointfor thermostat wiring, the interface board also translatesthermostat inputs into control commands for the variablespeed programmable ECM DC fan motor and displays anLED indication of operating status. The thermostatconnections and their functions are as follows:

NOTE: If the thermostat is provided with a malfunctionlight powered off of the common (C) side of thetransformer, the unit must be provided with a malfunctionrelay (FHP option # 660-006) to properly energize the light.The relay coil will be wired across the (ALR) and (C) contactson the unit’s UPM board and the relay’s normally opencontacts across (ALR) and the malfunction light connectionon the thermostat. If the thermostat is provided with amalfunction light powered off of the hot (R) side of thetransformer, then the thermostat malfunction lightconnection should be connected directly to the (ALR)contact on the unit’s UPM board.

To the left of the thermostat connection block are a row of2 red and 4 green LED’s. These LED’s indicate the operatingstatus of the unit. They are labeled as follows:

EM (red) Emergency Heat OnW1 (red) Auxiliary Heat OnO (green) Reversing Valve Energized, unit is

in cooling modeY2 (green) Second Stage Compressor OnY1 (green) First Stage Compressor OnG (green) Fan On

Just above the connector block is a single red LED labeledCFM that will blink intermittently when the unit is runningand may flicker when the unit is off. This LED indicates theair delivery of the blower at any given time. Each blink ofthe LED represent 100 CFM of air delivery so if the LEDblinks 12 times, pauses, blinks 12 times, etc. the blower isdelivering 1200 CFM. Refer to Figure #7 for factoryprogrammed air delivery settings for the ES Series.

To the right of the thermostat connection block is a greenLED labeled dehumidify.

Just above and to the right of the thermostat connectionblock are four sets of jumper pins labeled ADJ, DELAY, HEATand COOL. The ADJ set of pins are labeled NORM, (+), (-)and TEST. AP units will all be set on the NORM position fromthe factory, however, airflow can be increased (+) ordecreased (-) by 15% from the pre-programmed setting byrelocating the jumper in this section. The TEST position isused to verify proper motor operation. If a motor problemis suspected, move the ADJ jumper to the TEST position andenergize G on the thermostat connection block. If themotor ramps up to 100% power, then the motor itself isfunctioning normally. Always remember to replace thejumper to NORM, (+) or (-) after testing and reset the unitthermostat to restore normal operation.

NOTE: Do not set the ADJ jumper to the (-) setting whenelectric heaters are installed. Doing so may cause theheaters to cycle on their thermal overload switches,potentially shortening the life of the switches.

The other three sets of jumper pins are used to select theproper program in the ECM motor for the unit. Refer toFigure #7 for the proper jumper placement.

NOTE: Always disconnect power before changing jumperpositions on the interface board and reset the unitafterward.

To the left of the red and green status LED’s is a rowof 1/4” male quick connects. These are used to passthermostat inputs on to the rest of the controlcircuit. Remember to always turn off unit power atthe circuit breaker before attaching ordisconnecting any wiring from these connections toavoid accidental short circuits that can damage unitcontrol components.

SAFETY DEVICES AND THE UPM CONTROLLEREach unit is factory provided with a Unit Protection Module(UPM) that controls the compressor operation andmonitors the safety controls that protect the unit.

Safety controls include the following:

• High pressure switch located in the refrigerantdischarge line and wired across the HPC terminals onthe UPM

• Low pressure switch located in the unit refrigerantsuction line and wired across terminals LPC1 and LPC2on the UPM.

• Optional freeze protection sensor located on theleaving side of the water coil prevents unit operationbelow 35º F. A freeze stat pin located on the board maybe put in the YES or NO position depending whetherthe freeze stat is ordered.

NOTE: The factory default is in the YES position. If thefreeze stat option is not ordered the pin must be relocatedto the NO position.

• Optional Condensate overflow protection sensorlocated in the drain pan of the unit and connected tothe ‘cond’ terminal on the UPM board.

The UPM includes the following features:

• ANTI-SHORT CYCLE TIMER – 5 minute delay on breaktimer to prevent compressor short cycling.

• RANDOM START – Each controller has a uniquerandom start delay ranging from 270 to 300 seconds.

• LOW PRESSURE BYPASS TIMER - The low pressureswitch is bypassed for 120 seconds after compressorstart-up to prevent nuisance low pressure lockoutsduring cold start-up in the heating mode.

• BROWNOUT/SURGE/POWER INTERRUPTION PROTECTION –a 20 millisecond window is monitored for the abovecondition. Should any of these conditions be detected,

• MALFUNCTION OUTPUT – The controller has a set ofwet contacts for remote fault indication.

• TEST SERVICE PIN – A jumper pin is provided to reduceall time delay settings to 5 seconds duringtroubleshooting or verification of unit operation. Notethat operation of the unit in test mode can lead toaccelerated wear and premature failure of the unit.

• L.E.D. FAULT INDICATION – Two L.E.D. indicators areprovided:

• GREEN: Power L.E.D. indicates 18 – 30 VAC present atthe board.

• RED: Fault indicator with blink codes as follows:•• ONE BLINK High pressure lockout

•• TWO BLINKS Low pressure lockout

•• THREE BLINKS Freeze sensor lockout

•• FOUR BLINKS Condensate overflow

•• FIVE BLINKS Brown out

The fault pulse code may be sent to the ALR faultterminal by placing the Alarm Output pin in thepulse position. The pulse signal may be sent to athermostat with a fault indication LED (24v) andwill display the fault code on the thermostat.

• INTELLIGENT RESET - If a fault condition is initiated the5 minute delay on break time period and the randomstart timer are initiated and the unit will restart afterthese delays expire. During this period the fault LEDwill indicate the cause of the fault. If the fault conditionstill exists or reoccurs before 60 minutes, the unit will

go into a hard lockout and requires a manual lockoutreset. A condensate overflow fault will cause the unit togo into a hard lockout immediately.

• LOCKOUT RESET - A hard lockout can be reset byturning the unit thermostat off and then back on or byshutting off unit power at the circuit breaker.

NOTE: The blower motor will remain active during alockout condition.

ELECTRIC HEATER PACKAGE OPTION:Factory or field installed internal electric heater packagesare available for all Aquarius II series units. Two powersupplies are required when heater packages are utilized.The power supply for the heater package (located in theelectric heater package control box) provides power for theheater elements, the blower motor and the control circuitfor the unit. The power supply for the unit provides powerfor the compressor. This allows the electric heaters tocontinue to operate along with the blower motor in thecase of unit compressor and/or compressor power supplyfailure. See HP Series Heater Kit Instructions for fieldinstallation.

Each Aquarius II model has a number of heater sizesavailable. Refer to Figure #9 for heater packagecompatibility with specific Aquarius II units, modelnomenclature and electrical data.

30 seconds to ramp up to operating speed and will run atfan only rated air flow as long as there is no call forcompressor or heater operation.

When the thermostat calls for first stage cooling (Y1) theloop pump or solenoid valve if present is energized and thefirst stage of compressor capacity starts. The fan ramps upto first stage cooling air flow in 30 seconds.

When the thermostat calls for second stage cooling (Y2) thesecond stage (or full compressor capacity) is initiated. Thefan ramps up to full cooling air flow.

Once the thermostat is satisfied, the compressor shutsdown accordingly and the fan ramps down to either fanonly mode or off over a span of 30 seconds.

Note that a fault condition initiating a lockout will de-energize the compressor irrespective of which stage isengaged.

HEATING MODE:The first two stages of heating (Y1 & Y2) operate in thesame manner as cooling, but with the reversing valve de-energized. On a call for auxiliary heat (W1), the fan rampsup to auxiliary heat air flow immediately and the electricheater package is energized along with the compressor. Asthe thermostat is satisfied, the heaters will shut off as soonas W1 is de-energized, and the compressors will remain onuntil the thermostat stages are satisfied. Note that if theunit compressor lock out for any reason at this time, theelectric heaters will continue to function normally.

Once the thermostat is satisfied, the compressor shutsdown and the fan ramps down either fan only mode or offover a span of 30 seconds. If emergency heat (W2/EM) iscalled for, the fan will ramp up to emergency heat air flowimmediately and the heater package will energize inemergency heat mode, all heater elements coming on. Onshut down the fan will ramp down over a period of 30seconds.

WELL WATER SYSTEMS:(Figure #10)

Copper is adequate for ground water that is not high inmineral content. Should your well driller express concernregarding the quality of the well water available or shouldany known hazards exist in your area, we recommendproper testing to assure the well water quality is suitablefor use with water source equipment. In conditionsanticipating moderate scale formation or in brackish watera cupro-nickel heat exchanger is recommended. In wellwater applications water pressure must always bemaintained in the heat exchanger. This can beaccomplished with either control valve or a bladder typeexpansion tank. When using a single water well to supplyboth domestic water and the heat pump care must betaken to insure that the well can provide sufficient flow forboth. In well water applications a slow closing solenoidvalve must be used to prevent water hammer.

Solenoid valves should be connected across Y1 and C1 onthe interface board for all. Make sure that the VA draw ofthe valve does not exceed the contact rating of thethermostat.

INSTALLATION OF PRESSUREREGULATING VALVES:Pressure regulating valves are used to increase or decreasewater flow through the heat pump in response torefrigerant pressure. In some cases more water may berequired in heating than in cooling, or vice versa. With theAquarius II heat pumps these valves are not required.However, if installed, a pair of valves are required for properoperation, one valve for cooling (direct acting) and anothervalve for heating (indirect acting). A refrigerant tap isprovided in the refrigerant line located between thereversing valve and the water-to-refrigerant heatexchanger for proper monitoring of the refrigerantpressures.

The discharge water from the heat pump is notcontaminated in any manner and can be disposed of invarious ways depending on local building codes (i.e.discharge well, dry well, storm sewer, drain field, stream orpond, etc.) Most local codes forbid the use of a sanitarysewer for disposal. Consult your local building and zoningdepartment to insure compliance in your area.

COOLING TOWER/BOILER SYSTEMS:(Figure #11)

The cooling tower and boiler water loop temperature isusually maintained between 50˚ F to 100 ˚ F to assureadequate cooling and heating performance.

In the cooling mode, heat is rejected from the FHP unit intothe water loop. A cooling tower provides evaporativecooling to the loop water thus maintaining a constantsupply temperature to the unit. When utilizing opencooling towers, chemical water treatment is mandatory toensure the water is free from corrosive elements. Asecondary heat exchanger (plate frame) between the unitand the open cooling tower may also be used. It isimperative that all air be eliminated from the closed loopside of the heat exchanger to insure against fouling.

In the heating mode, heat is absorbed from the water loop.A boiler can be utilized to maintain the loop at the desiredtemperature.

CAUTION: Water piping exposed to extreme low ambienttemperatures is subject to freezing.

Consult the specification sheets for piping sizes. Teflontape sealer should be used when connecting to the unit toinsure against leaks and possible heat exchanger fouling.Do not overtighten the connections. Flexible hoses shouldbe used between the unit and the rigid system to avoidpossible vibration. Ball valves should be installed in thesupply and return lines for unit isolation and unit waterflow balancing. Pressure/temperature ports arerecommended in both supply and return lines for systemflow balancing. Water flow can be accurately set bymeasuring the water-to-refrigerant heat exchangers waterside pressure drop. See specification sheets for water flowvs. pressure drop information.

No unit should be connected to the supply or return pipinguntil the water system has been completely cleaned andflushed to remove any dirt, piping chips or other foreign

material. Supply and return hoses should be connectedtogether during this process to ensure the entire system isproperly flushed. After the cleaning and flushing has takenplace the unit may be connected to the water loop andshould have all valves wide open.

EARTH COUPLED SYSTEMS:(Figure #12)

Closed loop and pond applications require specializeddesign knowledge. No attempt at these installations shouldbe made unless the dealer has received specializedtraining. Utilizing FHP’s Ground Loop Pumping Package(GLP), makes the installation easy. Anti-freeze solutions areutilized when low evaporating conditions are expected tooccur. Refer to the GLP installation manuals for morespecific instructions.

SYSTEM CHECKOUT:• After completing the installation, and before

energizing the unit, the following system checksshould be made:

• Verify that the supply voltage to the heat pump is inaccordance with the nameplate ratings.

• Make sure that all electrical connections are tight andsecure.

• Check the electrical fusing and wiring for the correctsize.

• Verify that the low voltage wiring between thethermostat and the unit is correct.

• Verify that the water piping is complete and correct.

• Check that the water flow is correct, and adjust ifnecessary.

• Check the blower for free rotation, and that it issecured to the shaft.

• Verify that vibration isolation has been provided.

• Unit is serviceable. Be certain that all access panels aresecured in place.

UNIT START-UP:1. Set the thermostat to the highest setting.

2. Set the thermostat system switch to "COOL", and thefan switch to the "AUTO" position. The reversing valvesolenoid should energize. The compressor and fanshould not run.

3. Reduce the thermostat setting approximately 5degrees below the room temperature.

4. Verify the heat pump is operating in the cooling mode.

5. Turn the thermostat system switch to the "OFF"position. The unit should stop running and thereversing valve should deenergize.

6. Leave the unit off for approximately (5) minutes toallow for system equalization.

7. Turn the thermostat to the lowest setting.

8. Set the thermostat switch to "HEAT".

9. Increase the thermostat setting approximately 5degrees above the room temperature.

10. Verify the heat pump is operating in the heating mode.

11. Set the thermostat to maintain the desired spacetemperature.

12. Check for vibrations, leaks, etc...

MAINTENANCE:1. Filter changes or cleanings are required at regular

intervals. The time period between filter changes willdepend upon type of environment the equipment isused in. In a single family home, that is not underconstruction, changing or cleaning the filter every 60days is sufficient. In other applications such as motels,where daily vacuuming produces a large amount oflint, filter changes may be need to be as frequent asbiweekly.

WARNING: Equipment should never be used duringconstruction due to likelihood of wall board dustaccumulation in the air coil of the equipment whichpermanently affects the performance and may shortenthe life of the equipment.

2. An annual “checkup” is recommended by a licensedrefrigeration mechanic. Recording the performancemeasurements of volts, amps, and water temperaturedifferences (both heating and cooling) isrecommended. This data should be compared to theinformation on the unit’s data plate and the data takenat the original startup of the equipment.

3. Lubrication of the blower motor is not required,however may be performed on some motors to extendmotor life. Use SAE-20 non-detergent electric motoroil.

4. The condensate drain should be checked annually bycleaning and flushing to insure proper drainage.

5. Periodic lockouts almost always are caused by air orwater flow problems. The lockout (shutdown) of theunit is a normal protective measure in the design of theequipment. If continual lockouts occur call a mechanicimmediately and have them check for: water flowproblems, water temperature problems, air flowproblems or air temperature problems. Use of thepressure and temperature charts for the unit may berequired to properly determine the cause.

TROUBLE SHOOTING

PROBLEM POSSIBLE CAUSE CHECKS AND CORRECTIONS

ENTIRE UNIT DOESNOT RUN

Power supply off Apply power, close disconnect

Blown fuse Replace fuse or reset circuit breaker. Check for correct fuses.

Voltage supply low If voltage is below minimum voltage specified on unit data plate, contact local power company.

Thermostat Set the fan to "ON", the fan should run. Set thermostat to "COOL" and lowest temperature setting,the unit should run in the cooling mode (reversing valve energized). Set unit to "HEAT" and thehighest temperature setting, the unit should run in the heating mode. If neither the blower orcompressor run in all three cases, the thermostat could be miswired or faulty.To ensure miswiredor faulty thermostat verify 24 volts is available on the condensing section low voltage terminalstrip between "R" and "C", "Y" and "C", and "O" and "C". If the blower does not operate, verify 24volts between terminals "G" and "C" in the air handler. Replace the thermostat if defective.

BLOWER OPERATESBUT COMPRESSORDOES NOT

Thermostat Check setting, calibration, and wiring.

Wiring Check for loose or broken wires at compressor, capacitor, or contactor.

Safety controls Check UPM board red default L.E.D. for Blink Code

Compressor overload open If the compressor is cool and the overload will not reset, replace compressor.

Compressor motor grounded Internal winding grounded to the compressor shell. Replace compressor. If compressor burnout,install suction filter dryer.

Compressor windings open After compressor has cooled, check continuity of the compressor windings. If the windings areopen, replace the compressor.

UNIT OFF ONHIGH PRESSURECONTROL

Discharge pressure too highIn "COOLING" mode: Lack of or inadequate water flow. Entering water temperature too warm.Scaled or plugged condenser.In "HEATING" mode: Lack of or inadequate air flow. Blower inoperative, clogged filter orrestrictions in ductwork.

Refrigerant charge The unit is overcharged with refrigerant. Reclaim refrigerant, evacuate and recharge with factoryrecommended charge.

High pressure Check for defective or improperly calibrated high pressure switch.

UNIT OFF ONLOW PRESSURECONTROL

Suction pressure too low In "COOLING" mode: Lack of or inadequate air flow. Entering air temperature too cold. Blowerinoperative, clogged filter, or restrictions in ductwork.In "HEATING" mode: Lack of or inadequate water flow. Entering water temperature too cold.Scaled or plugged condenser.

Refrigerant charge The unit is low on refrigerant. Check for refrigerant leak, repair, evacuate and recharge withfactory recommended charge.

Low pressure switch Check for defective or improperly calibrated low pressure switch.

UNIT SHORTCYCLES

Unit oversized Recalculate heating and or cooling loads.

Thermostat Thermostat installed near a supply air grill, relocate thermostat. Readjust heat anticipator.

Wiring and controls Loose connections in the wiring or a defective compressor contactor.

INSUFFICIENTCOOLING ORHEATING

Unit undersized Recalculate heating and or cooling loads. If excessive, possibly adding insulation and shading willrectify the problem.

Loss of conditioned airby leaks

Check for leaks in duct work or introduction of ambient air through doors or windows.

Airflow Lack of adequate air flow or improper distribution of air. Replace dirty filter.

Refrigerant charge Low on refrigerant charge causing inefficient operation.

Compressor Check for defective compressor. If discharge is too low and suction pressure is too high,compressor is not pumping properly. Replace compressor.

Reversing valve Defective reversing valve creating bypass of refrigerant from discharge to suction side ofcompressor. Replace reversing valve.

Operating pressures Compare unit operating pressures to the pressure / temperature chart for the unit.

TXV Check TXV for possible restriction or defect. Replace if necessary.

Moisture, noncondensables The refrigerant system may be contaminated with moisture or noncondensables. Reclaimrefrigerant, evacuate and recharge with factory recommended charge. Note: a liquid line dryermay be required.
